Credential transfer management camera system

ABSTRACT

A camera detects devices, such as other cameras, smart devices, and access points, with which the camera may communicate. The camera may alternate between operating as a wireless station and a wireless access point. The camera may connect to and receive credentials from a device for another device to which it is not connected. In one embodiment, the camera is configured to operate as a wireless access point, and is configured to receive credentials from a smart device operating as a wireless station. The camera may then transfer the credentials to additional cameras, each configured to operate as wireless stations. The camera and additional cameras may connect to a smart device directly or indirectly (for instance, through an access point), and the smart device may change the camera mode of the cameras. The initial modes of the cameras may be preserved and restored by the smart device upon disconnection.

BACKGROUND Technical Field

This disclosure relates to a camera management system, and morespecifically, to the detection of devices by a camera system, thepassing of credentials between cameras and other devices, and themanagement of camera operation modes.

Description of the Related Arts

The technological advancement of cameras has progressed immensely inrecent years. Cameras have recently begun to include features, such aswireless communication capabilities, previously unavailable to cameras.The incorporation of wireless communication capabilities into camerasprovides a means for cameras to communicate with other devices.

Cameras may operate in a plurality of modes when communicating withother devices. One such mode allows a camera to operate as a wirelessaccess point for one or more other devices (hereinafter, “access pointmode”). Another such mode allows a camera to operate as a wirelessstation (hereinafter, “station mode”). Typically, connections betweentwo wireless devices require at least one of the devices to be in accesspoint mode; in such instances, two devices in station mode cannotconnect to each other. The remainder of the description herein willoperate under the assumption that at least one device must be in accesspoint mode in order to establish a connection between two devices.Finally, cameras may operate as intermediaries between devices instation mode and devices in access point mode by receiving and/orforwarding communications between such devices (hereinafter, “ad hocmode”). Collectively, access point mode, station mode, and ad hoc modeare referred to herein as “communication modes.” It should be noted thatgenerally a device operating in station mode may only connect to asingle device, whereas a device operating in access point mode or ad hocmode may connect to any number of other devices, including multipledevices operating in station mode.

The various communication modes available to cameras and the limitationsof such modes impose a variety of challenges that must be addressed whendesigning camera-based systems. In addition, the operation of cameraswithin such a system requires a management system to satisfy therequirements of communications standards, particularly during thedetection of devices in such a camera system and in the transfer ofcredentials between the devices.

Overview

An image capture system provides photographers, professional andamateur, a configuration for capturing images and video at highresolutions and frame rates. The cameras described herein may beconsumer grade while the configuration of the cameras allows for thewireless transfer of data between the cameras and other devices withoutthe expense of professional grade equipment.

The camera system described herein allows consumers to capturehigh-resolution and high-frame rate images and video of local events oractivities, including sporting events, theater performances, concerts,weddings, or other events without requiring a professional photographerand advanced camera equipment. It should be noted that for the purposesdescribed herein, video capture is performed by the capture ofsuccessive images (“frames”), and thus functionality described hereinmaking reference to one of either video capture or image capture isapplicable to both.

The cameras described herein may include various camera settings(referred to herein as “camera modes” or “operation modes”). Examplecamera modes include various video recording modes (such as a normalvideo recording mode and a high-speed video recording mode, etc.),various video playback modes (such as a normal video playback mode, ahigh-speed playback mode, a slow-motion playback mode, a paused videomode and the like), various image capture modes (normal image capture,timed image capture, rapid-successive multiple-image capture, etc.), andvarious image playback modes (normal captured image display,multiple-image display, slideshow image display, etc.).

In addition, the cameras may include various camera modes related tocamera properties. In one embodiment, the camera modes include variousimage resolutions for capture and playback, such as 300×480, 480×360,640×480, 768×576, 720×480, 1280×720, 1280×960, 1440×1080, 1920×1080,2048×1080, 4096×2160, 7680×4320, any other industry standard resolution,or any other resolution. Likewise, the camera modes may include variousvideo resolutions for capture and playback, such as 480i/p, 576i/p,720p, 1080i/p, any other industry standard resolution, or any otherresolution. The cameras may include camera modes for various capture andplayback aspect ratios (such as 4:3, 16:9, and the like) and variousframe capture and playback frame rates (such as 15 fps, 24 fps, 30 fps,45 fps, 60 fps, 90 fps, 120 fps, and the like). The cameras may alsoinclude camera modes for various color, brightness, contrast, and audiosettings, and may include many auto-detect modes for detecting the idealsettings for image and video capture given the camera's context (such asa night mode, a long distance mode, a people mode, a scenery mode, anunderwater mode, and the like).

The camera may include various camera modes related to data transfer. Inone embodiment, the cameras include camera modes for starting andstopping the streaming of previously captured image or video data, orfor image and video data in the process of being captured. For example,a camera mode may allow a camera to stream video being captured toanother device, while another camera mode may allow the camera to streampreviously captured images to a cloud storage system, a photo or videowebsite, or a social network.

The camera may include various camera modes related to image and videoediting. In one embodiment, the cameras include camera modes for editingpreviously captured images, allowing a user to, for example, increasethe brightness of an image, crop an image, resize an image, removefeatures from an image, reduce image “redeye”, and the like. Similarly,the cameras may include camera modes for editing previously capturedvideo, allowing a user to, for example, change the contrast of thevideo, change the video frame rate, crop the video, increase ordecreased the volume of the capture audio, include external audio (suchas a music track) in the video, and the like.

A camera may include various camera modes related to the mechanicaloperation of the camera. In one embodiment, the cameras include zoom inand zoom out modes for adjusting the zoom of the camera lenses.Similarly, the cameras may include exposure time modes for adjusting thelength of the exposure of a scene before a camera onto the camera'simage sensor. A camera may include camera modes related to the focallength of the camera or the F-number of the camera. A camera may includevarious flash modes, for instance a no-flash mode, an always-flash mode,or a flash autodetect mode. A camera may include any other camera moderelated to the camera, the setting or context of the camera, the user ofthe camera, image or video capture, image or video playback, datastreaming, camera mechanical functionality, or any other aspect ofcamera use. A camera may also include the means to allow the remoteadjustment of the physical position, rotation, or orientation of thecamera (for instance via a mechanical engine for re-positioning thecamera).

The camera in the camera system described herein beneficially switchesbetween communication modes in order to detect devices operating invarious wireless modes. Certain devices are only able to operate incertain modes. For example, many mobile phones are only capable ofoperating in station mode. Accordingly, in order to connect to suchmobile phones, the camera must switch to access point mode or ad hocmode. Likewise, certain devices, such as wireless receiver andtransmitter devices (for instance, routers, mobile phone towers,switches, and the like), may operate as dedicated access points.Accordingly, in order to connect to such access points, the camera mayoperate in station mode. It should be noted that in one embodiment, inorder for a device configured to operate in access point mode to detectand connect to a device configured to operate in station mode, theaccess point mode device sends out a beacon signal identifying andindicating the availability of the access point mode device, and thestation mode device, upon receiving this beacon signal, requests aconnection to the access point mode device. Although in such anembodiment it is the station mode device that initiates the connectionrequest between the devices, the description herein may describe eitherthe access point mode device or the station mode device as theconnecting or connection-instigating device.

In one embodiment, it is desirable for a camera in such camera systemsto operate in station mode, as station mode may require less power thanaccess point mode or ad hoc mode, and as a result, the camera is suchcamera systems operate in station mode by default. Users of the camerasystem may not understand the difference between wireless communicationmodes, and may not appreciate the limitations of each; accordingly, itmay be desirable for a camera in a camera system to automatically switchbetween communication modes in order to automatically wireless devicesregardless of the communication mode of the wireless devices.

Communication between wireless devices often requires one of the devicesto possess information about the other device. For example,communication between wireless devices may require a first device toknow the name of a second device, to know the IP or MAC address of thesecond device, an access password of the second device, an encryptionmethod of the second device, a communication format or protocol of thesecond device, any communication timing requirements of the seconddevice, a user account associated with the second device, a network nameor identity associated with the second device, or any other property ofthe second device. This information is referred to collectively hereinas the “credentials” or “credential information” of a wireless device. Adedicated access point, such as a router, a modem, a cell phone tower,and the like, require other devices to send the credentials of theaccess point to the access point prior to communicating with the accesspoint. A device may contain the credentials of another device (forinstance, the credentials may be programmed into the device by amanufacturer, may have been previously entered and stored for subsequentuse, and the like), or the credentials of the other device may beobtained (for instance, by a user's manual entry). Generally, a wirelessdevice must obtain the credentials of another device prior tocommunicating with the other device, though in some embodiments, devicesmay connect and communicate without obtaining each other's credentials.

Often, cameras lack sophisticated input devices and interfaces. Forexample, while typical computers have keyboards and mice, and whilephones have keypads, camera inputs are often limited to a few buttons.Sport cameras may have as few as one or two buttons. The lack of asophisticated input interface may limit the ability of a user to enterinformation into a camera. Accordingly, entering device credentials intoa camera with such a limited input interface manually may be frustratingand time-consuming at best, and prohibitively difficult at worse.

Detecting Wireless Devices

FIG. 1 is a block diagram illustrating an embodiment of a camera system.In the embodiment of FIG. 1, a camera 100 communicates with otherwireless devices, such as a smart device 110 and an access point 120. Inorder to wirelessly communicate with other devices, the camera 100 mustfirst detect the other devices to which the camera 100 can wirelesslycommunicate. The camera 100 may ping wireless devices over a range ofwireless frequencies and wireless modes in order to detect devicescapable of wirelessly communicating with the camera 100. Alternatively,the camera 100 may know in advance the frequencies and wireless modes ofother devices, and may examine these frequencies and modes to detectwireless devices. As discussed below, the camera 100, in response todetecting one or more wireless devices, may attempt to connect with theone or more wireless devices.

In order to detect other wireless devices, the camera 100 may send out aquery ping signal over a communicative range of the camera 100. Thecommunicative range of the camera 100 is the range over which the camera100 can transmit signals and maintain signal integrity. The query signaltransmitted by the camera 100 may be configured to cause any wirelessdevices in the communicative range of the camera 100 to respond with anidentifying signal. The identifying signal may include variousinformation, such as information about the identity of the wirelessdevice, information about the communicative mode or the operating modeof the wireless device, information about the availability of thewireless device, and so forth. As used herein, “availability” refers tothe ability of the wireless device to be detected, connect to, andcommunicated with. By receiving the identifying signal, the camera 100is able to identify the wireless device, and may be able to determinethe communicative mode and availability of the wireless device. Thus,the camera 100 may detect any of number of wireless devices by sendingout a query signal and receiving an identifying signal from any or allof the wireless devices within the communicative range of the camera100. The query signal may be configured to cause only wireless devicesconfigured in a particular operation mode to send an identifying signal(such as devices configured to operate as wireless access points ordevices configured to operate as wireless stations).

In one embodiment, the camera 100 detects and communicates with otherdevices using the IEEE 802.11 WiFi protocol. In this embodiment, thecamera 100 detects other devices in the WiFi pre-association/associationmode (hereinafter, simply “association mode”). During association mode,the camera 100 configures itself to detect and associate with one ormore other WiFi devices. As discussed above, some devices are configuredto only operate in station mode; such devices can only communicate withdevices in access point mode or ad hoc mode. In one embodiment, thesmart device 110 is such a device, and thus in order to communicate withthe camera 100, the camera 100 must be configured to operate in accesspoint mode or ad hoc mode. Accordingly, the association mode of thecamera 100 may be configured such that the camera 100 switches betweenaccess point mode and station mode, or between access point mode, ad hocmode, and station mode.

In some embodiments, it is preferable for wireless devices to operate instation mode, which requires less power and processing power than accesspoint mode or ad hoc mode. Accordingly, the camera 100 may initialize tostation mode, may cycle from station mode through access point modeand/or ad hoc mode (to detect devices configured to operate in stationmode), and may return to station mode. Such a configuration maximizesthe amount of time the camera 100 is configured to operate in stationmode, and thus optimizes the power performance and efficiency of thecamera 100. While the camera 100 is in access point mode or ad hoc mode,it may be configured to constantly scan for new devices. Likewise, whenthe camera 100 initializes to station mode, or when it returns tostation mode after cycling through modes, the camera 100 may constantlyor periodically scan for new devices.

The camera 100 may cycle between access point mode, ad hoc mode, andstation mode in response to an input from a user. For example, thecamera 100 may have a “detect devices” input, or an “association mode”input, which causes the camera 100 to cycle through configuration modes.Alternatively, the camera 100 may automatically cycle between modes, forexample, when the camera 100 is in station mode and has not detected anydevices after a pre-determined amount of time has passed. In such anembodiment, the camera 100 may periodically cycle between modes eachtime a predefined time period elapses, e.g., 10 minutes, withoutdetecting additional devices. In one embodiment, each time the camera100 cycles between modes and does not detect other devices, the periodof time between each subsequent cycling between modes increases. Forexample, after the first time the camera 100 cycles between access pointmode, ad hoc mode, and station mode, the camera 100 may wait 5 minutesbefore again cycling between modes; after the second cycle withoutdetecting devices, the camera 100 may wait 10 minutes, after the thirdcycle, the camera 100 may wait 15 minutes, and so on.

When cycling between station mode, access point mode, and ad hoc mode,the camera 100 may detect and attempt to connect with other devices. Thecamera 100 may detect devices configured to only operate in station modewhen the camera 100 is in access point mode or ad hoc mode. Thus, in theembodiment where the smart device 110 is configured to only operate instation mode, the camera 100 can still detect the smart device 110 whenthe camera 100 cycles to access point mode or ad hoc mode, despite thecamera 100 being configured to operate in station mode a majority of thetime.

When cycling between communication modes, the camera 100 may spend apre-determined amount of time configured to operate in access point modeand ad hoc mode before returning to station mode. For example, if thecamera 100 switches to access point mode, if the camera 100 has notdetected other devices within 10 seconds, the camera 100 may switch toad hoc mode for 10 seconds, and may return to station mode if devicesare not detected while in ad hoc mode. In one embodiment, if the camera100 detects other devices in either access point mode or ad hoc mode,the camera 100 may remain configured in access point mode or ad hoc modeuntil communication with the detected other devices is completed. Whencommunication with a device configured to operate in station mode iscompleted, the camera 100 may (prior to returning to station mode)remain configured in access point mode or ad hoc mode for apre-determined amount of time, in order to detect and communicate withother devices configured to operate in station mode.

After cycling through access point mode and ad hoc mode, the camera 100reverts to station mode and may detect devices configured to operate inaccess point mode or ad hoc mode. For example, if the camera 100 failsto detect devices while in access point mode and/or ad hoc mode, orafter the camera 100 is finished communicating with devices while inaccess point mode and/or ad hoc mode, the camera 100 switches to stationmode, at which point it can connect to the access point 120. While thecamera 100 may be able to connect to the access point 120 while inaccess point mode or ad hoc mode itself, such a configuration is lesspower-efficient than if the camera 100 connects to the access point 120while the camera 100 is in station mode. If the camera 100 detects thatthe access point 120 or any other device is configured to operate inaccess point mode, the camera 100 may delay connecting to the accesspoint 120 or other device until the camera 100 is in station mode. Inone embodiment, the camera 100 may attempt to detect other devices in aparticular communication mode (such as access point mode), and upondetecting devices, may determine if any detected devices are trusteddevices, such as previously known devices, a particular type or model ofdevice, devices manufactured by a particular company, devices associatedwith a particular IP address or MAC address, devices includingparticular credentials or other characteristics, and the like. In thisembodiment, if no devices are detected, or if no detected devices aretrusted devices, the camera 100 can cycle to a different communicationmode (such as station mode) and attempt to detect devices in the newcommunication mode.

Once the camera 100 detects other devices to which it can communicate,the camera 100 may attempt to establish a connection with the detecteddevices. In one embodiment, the camera 100 may establish a connectionwith another device only if both the camera and the other device are inan association mode. In such an embodiment, both the camera and theother device are configured to establish a connection with devices alsoin an association mode. In order to ensure both the camera 100 and theother device are in an association mode, a user may input a command toenter an association mode on both devices. Configuring the camera 100 tocycle through access point mode, ad hoc mode, and station mode may causethe camera 100 to enter association mode. Likewise, pressing a button orinterfacing with another form of input on the other device may cause theother device to enter association mode. Alternatively, the camera 100and a device may each have a synchronization (or “synch”) mode which maybe triggered by a user, or which may trigger automatically, causing thecamera 100 and device to connect when synchronized.

Establishing a connection between the camera 100 and a detected deviceinvolves the passing of the credentials of the detected device from thecamera 100 to the detected device, or vice versa. In one embodiment, inorder to establish a connection between the camera 100 and the detecteddevice, the camera 100 must have the credentials of the detected device,and the detected device must have the credentials of the camera.Alternatively, in another embodiment, a detected device may beconfigured such that the camera 100 may connect to the detected devicewithout the passing of credentials. In the event that the camera 100does not possess the credentials of a detected device and still attemptsto connect to the detected device requiring such credentials, theconnection may be denied, or the detected device may prompt the camerato obtain the credentials of the detected device. It should be notedthat “providing credentials” may not involve the explicit transmissionof the credentials of a detected device to the detected device, but mayinstead involve the mere use of information contained within thecredentials to identify the camera 100 to the detected device or tofollow a particular protocol required by the detected device in order toconnect to the detected device.

In one embodiment, the camera 100 can detect other cameras. For example,if the camera 100 is configured to operate in access point mode, and oneor more other cameras are configured to operate in station mode, thecamera 100 may detect and attempt to connect to the one or more othercameras. The devices to which the camera 100 may detect and connect maybe limited. Likewise, the devices able to detect and connect to thecamera 100 may be limited. For instance, a manufacturer may program thecamera 100 to detect and connect to only devices made by themanufacturer. Alternatively, an owner of the camera 100 may limit thedevices to which the camera 100 can detect and connect to onlycommonly-owned devices. The devices to which the camera 100 may detectand connect to may be limited based on Internet Protocol (“IP”) or MediaAccess Control (“MAC”) address (for instance, the camera 100 may includea list of IP or MAC addresses associated with devices to which thecamera 100 may connect, or to which the camera 100 may not connect). Inone embodiment, the camera 100 is configured to use the multicast domainname system (mDNS) protocol to detect devices to which to connect.Likewise, the devices to which the camera 100 may detect and connect tomay be limited based on password (for instance, the camera 100 mayinclude a password that another device must possess in order to connectto the camera 100). In one embodiment, a camera 100 is configured tohide the service set identifier (SSID) associated with the camera 100,preventing other devices from detecting the camera 100. In thisembodiment, the camera 100 may be configured to allow a user to unhidethe SSID of the camera 100 (for instance, by pressing a button orentering an input associated with unhiding the SSID of the camera 100),allowing other devices to detect the camera 100 for a period of time.

Obtaining Wireless Credentials

The camera 100 may obtain the wireless credentials of another device ina number of ways. In one embodiment, the camera 100 may obtain thewireless credentials of a first wireless device wirelessly from a secondwireless device. In the example embodiment of FIG. 1, the camera 100receives credentials for an access point 120 from a smart device 110.The access point 120 may be any device able to communicate wirelessly inaccess point mode, such as a wireless router, a Wifi/WiMax access point,a cell phone tower, a computer, a mobile phone, and the like. The smartdevice 110 may be any device capable of communicating with the camera100, such as a mobile phone, a computer, a tablet, a remote control, andthe like. In one exemplary embodiment, the smart device 110 is a smartphone and the access point 120 is a cell phone or mobile phone tower.

It is presumed in the embodiment of FIG. 1 that the camera 100 is ableto initially communicate with the smart device 110. In the event thatthe camera 100 and the smart device 110 communicate wirelessly, this mayrequire the camera 100 to initially possess the credentials of the smartdevice 110, or vice versa. In such an embodiment, the manufacturers ofthe camera 100 may include the credentials for the smart device 110 inthe camera 100 (e.g. by pre-configuring the camera with thecredentials), or the user of the camera 100 may manually upload thecredentials of the smart device 110 to the camera 100 (e.g., using aprogram and input means associated with the smart device 110 to enterthe credentials and transfer the credentials to the camera 100).Alternatively, the camera 100 and the smart device 110 may be configuredto synchronize to each other via user input, via mutual credentialpassing, via a pre-determined synchronization protocol, via a wiredconnection, and the like. It is also presumed that the camera 100 doesnot initially possess the wireless credentials of the access point 120,and thus is not initially able to communicate with the access point 120apart from detecting the presence of the access point 120.

The camera 100 is configured to request the credentials of the accesspoint 120 from the smart device 110. In one embodiment, the camera 100requests credentials for the access point 120 in response to detecting,attempting to connect to, and being denied by the access point 120. Therequest 134 sent by the camera 100 identifies the access point 120 tothe smart device 110. The request 134 may contain additionalinformation, such as the identity of the camera 100, the identity of auser of the camera 100, login or user account information for the smartdevice 110, or any other information that may be used by the smartdevice 110 to obtain user credentials for the access point 120.

The smart device 110 is configured to receive requests for credentialinformation from the camera 100 and to provide credential information tothe camera 100. The smart device 110 may be configured to verify theidentity of the camera 100 or the user of the camera 100 based on theinformation contained within the request 134, prior to providing orrequesting the credentials of the access point 120. The smart device 110identifies the requested credentials, for instance based on theidentified access point 120 in the request 134. In one embodiment, thesmart device 110 already possesses the credentials for the access point120 prior to receiving the request 134. For instance, the smart device110 may have previously received and stored the credentials of theaccess point 120. In such an embodiment, the smart device 110 sends thecredentials 136 to the camera 100.

In the event the smart device 110 does not possess the credentials ofthe access point 120, the smart device requests the credentials from theaccess point 120. The request 132 identifies the smart device 110 to theaccess point 120. In one embodiment, the request 132 includes theidentity of the smart device 110, the identity of the camera 100, theidentity of the user of the camera 100, login or user accountinformation used to access the access point 120, or any otherinformation used by the access point 120 to provide credentials for theaccess point 120 to the smart device 110. The access point 120 and thesmart device 110 may communicate wirelessly or via other means. Thecredentials are provided by the access point 120 to the smart device 110as the credentials 130, and are then provided by the smart device 110 tothe camera 100 as the credentials 136.

In one example embodiment, the camera 100 and the smart device 110communicate wirelessly, and the smart device 110 is configured to onlyoperate in station mode. In such an embodiment, the camera 100 mayinitially detect the access point 120 while the camera 100 is operatingin station mode. The access point 120 may deny a connection request fromthe camera 100, and the camera 100 may switch to access point mode. Thecamera 100 may detect and connect to the smart device 110 operating instation mode, and may request the credentials of the access point 120.In response to receiving the credentials for the access point 120 fromthe smart device 110, the camera 100 may switch back to station mode,and may re-attempt to connect to the access point 120 using thecredentials received from the smart device 110. In an example of thisembodiment, the smart device 110 is a smart phone, and a user mayrequest and receive the credentials for a wireless router from the smartphone by switching a camera to access point mode or ad hoc mode,connecting to the smart phone, receiving the credentials from the smartphone, switching back to station mode, and connecting to the wirelessrouter using the credentials.

Alternatively, the camera 100 may connect to and receive credentialsfrom the smart device 110 via a wired connection. In one embodiment, thecamera 100 may connect to the smart device 110 via USB or Ethernetcable, or via other wired means. The camera 100 and the smart device 110may contain interfaces that allow credentials to be stored on andretrieved from a removable non-transitory computer-readable storagemedia, e.g., a memory card or disk drive. The camera 100 and the smartdevice 110 may communicate and pass credentials for the access point 120via a wireless interface, e.g., an infrared or Bluetooth wirelessconnection.

In one embodiment, the smart device 110 includes an audio jack and isconfigured to encode the credentials of the access point 120 into anaudio signal. In this embodiment, the camera 100 is configured to coupleto the smart device 110 via the audio jack, and to receive the audiosignal including the encoded credentials. The camera 100 is furtherconfigured to decode the received audio signal to obtain the credentialsfor the access point 120. The smart device 110 may encode thecredentials into an audio signal using any suitable encoding means ormethod, for example by transforming data representing the credentialsinto a series of audio frequencies using a mapping that maps sequencesof bits to frequencies. The camera 100 may decode an audio signalencoded in such a way using the same mapping.

In one example embodiment, the smart device 110 is configured to encodethe credentials of the access point 120 into an audio signal, and isfurther configured to play this audio signal on a speaker of the smartdevice 110. In this embodiment, the camera 100 is configured to receiveand capture the played audio signal at a microphone on the camera 100.The camera 100 is then configured to decode the captured audio signal toobtain the credentials of the access point 120.

In one example embodiment, the smart device 110 is configured to encodethe credentials of the access point 120 into an image, and to displaythe image to the camera 100. In this embodiment, the camera 100 isconfigured to take a picture of the displayed image, and to decode thecaptured image to obtain the credentials of the access point 120. Thesmart device 110 may use any suitable means or method to encodecredentials into an image, such as a barcode, a QR code, and the like.

Once the camera 100 receives the wireless credentials for the accesspoint 120 from the smart device 110, the smart device 110 may providethe credentials to other cameras, or the camera 100 may be configured toprovide these credentials to other cameras. FIG. 2 is a block diagramillustrating an embodiment of a camera system. In the embodiment of FIG.2, the camera 100 receives the credentials 200 for the access point 120from the smart device 110, and provides the credentials 202 a, 202 b,and 202 c (collectively, the “credentials 202”) to the cameras 105 a,105 b, and 105 c (collectively, the “cameras 105”), respectively. In theembodiment of FIG. 2, only three cameras 105 are displayed; otherembodiments may have any number of cameras, for example 50 or 100.

In one example embodiment, the smart device 110 is unable to operate inany wireless mode other than station mode, requiring the camera 100 tobe configured to operate in access point mode or ad hoc mode in order tobe able to receive the credentials 200 wirelessly. In this embodiment,the camera 100 may remain in access point mode or ad hoc mode to detectand connect to the cameras 105 operating in station mode. In such anembodiment, the camera 100 may connect to the cameras 105 and pass thecredentials 202 simultaneously. After the camera 100 passes thecredentials 202 to the cameras 105, the camera 100 may then switch tostation mode for connecting to the access point 120.

The camera 100 may instead switch to station mode prior to connecting tothe cameras 105, though such a configuration would require each of thecameras 105 to be operating in access point mode or ad hoc mode prior toconnecting. This configuration may not be preferable, as it may resultin more cameras operating in less-efficient modes. In addition, asdevices operating in station mode can generally only connect to oneother device at a time, this configuration would require the camera 100to connect to each of the cameras 105 individually, resulting in a lesstime-efficient credential-passing process, particularly in embodimentswith large numbers of cameras 105.

Once the camera 100 and each of the cameras 105 possess the credentialsfor the access point 120, the cameras 100, 105 may connect to the accesspoint 120. As discussed above, connecting to the access point 120 mayrequire the cameras 105 passing the credentials as credentials 204 a,204 b, and 204 c (collectively, the “credentials 204”) to the accesspoint 120, and the camera 100 to pass the credentials as credentials 206to the access point 120. Prior to connecting to the access point 120,the camera 100 and the cameras 105 may switch to station mode in orderto improve the power efficiency of the cameras. It should be noted thatwhen each of the cameras 100, 105 receive the credentials for the accesspoint 120, the cameras 100, 105 may store the credentials for later usein connecting to and communicating with the access point 120, preventingthe need for re-obtaining the credentials from the smart device 110 at alater point in time. Beneficially, by receiving the credentials from thesmart device 110, the camera 100 is able to receive the credentials ofthe access point 120 without the need for a display, and with the use ofa minimal user input.

Control of Camera by Smart Device

The camera 100 and the smart device 110 may be configured to connect toeach other, and may be further configured such that the smart device 110may provide an interface for controlling various functionalities of thecamera 100 and for receiving various data from the camera 100(hereinafter “controlling” a camera). In one embodiment, the smartdevice 110 may provide an interface for controlling the camera 100 whilethe smart device 110 and the camera 100 are connecting during therequesting, retrieval, and passing of credentials from the smart device110 to the camera 100. Alternatively, the smart device 110 may providean interface for controlling the camera 100 at any other time the smartdevice 110 is connected to the camera 100, for instance in response toan input from a user of the camera 100 or the smart device 110 toconnect the camera 100 and the smart device 110.

In the embodiments of FIG. 1 and FIG. 2, the smart device 110 isconfigured to operate in station mode, resulting in a configurationwhere the smart device 110 is only able to connect to (and control) onecamera (for instance, camera 100) at a time when directly connected tothe camera. Alternatively, the smart device 110 may be configured toconnect to multiple cameras indirectly, for example, by connecting tothe cameras through the access point 120 as illustrated in FIG. 3.

FIG. 3 is a block diagram illustrating an embodiment of the camerasystem. The embodiment of FIG. 3 includes a camera 100, cameras 105 a,105 b, and 105 c, a remote control 340, a smart device 110 running anapplication 300, and an access point 120. In the embodiment of FIG. 3,the smart device 110, operating in station mode, connects to the accesspoint 120, operating in access point mode, which in turn connects toeach of the camera 100 and the cameras 105. In this embodiment, smartdevice 110 is said to logically connect to the cameras 100, 105 via theaccess point 120. The smart device 110 may control each of the camerasby sending commands to the cameras and receiving data from the camerasthrough the access point 120, which routes communications and data fromthe smart device 110 to the cameras and vice versa. As discussed above,since the access point 120 is configured to operate in access pointmode, multiple cameras may connect to the access point 120simultaneously, overcoming the limitation of the smart device 110 beingable to connect to only one other device when operating in station mode.

In the embodiment of FIG. 3, the smart device 110 may be configured tocontrol all of the cameras simultaneously, or may be configured tocontrol just a subset of the cameras at a time.

For instance, the smart device 110 may instruct all connected cameras tobegin recording simultaneously, and may subsequently instruct one or twocameras to stop recording while the remaining cameras continuerecording. The functionality of the control interface of the smartdevice 110 will be discussed below in greater detail.

The smart device 110 may connect to one or more cameras, e.g. cameras100, 105, via additional means or mechanisms for the purposes ofcontrolling the one or more cameras. For example, the smart device 110may control a camera when connected to the camera via USB or Ethernetcable. Likewise, the smart device 110 may control a camera when thecamera is connected to an audio jack on the smart device 110. Finally,the smart device 110 may control a camera, e.g. cameras 100, 105, whenthe camera is connected to the smart device 110 via IR or Bluetooth. Inthese embodiments, the smart device 110 may send data to and receivedata from one or more cameras via the means of connection between thecameras and the smart device 110. Note that these connectiontechnologies may limit the distance between the smart device 110 and oneor more cameras, potentially reducing the effectiveness of such asystem.

The smart device 110 may be used to control one or more cameras, e.g.cameras 100, 105, to which the smart device is connected in a number ofways. In one embodiment, the smart device 110 may be configured tochange the camera modes and settings on one or more of the camerascontrolled by the smart device 110. For example, the smart device 110may change all connected cameras to a “record 1080p video” mode, maycause a subset of the cameras to zoom in, may cause a subset of thecameras to use flash, may switch half the cameras to night mode, and maycause one camera to stream captured video to a cloud storage server. Inanother example, the smart device 110 may cause each camera to streamlive captured video to the smart device 110 for real-time editing anddisplay on the smart device 110 (or on a display coupled to the smartdevice) by a user of the smart device 110. Various additional examplesof camera modes and settings are described above. It should be notedthat the smart device 110 may change camera modes and settings anynumber of times, for instance, as requested by a user of the smartdevice 110.

In one embodiment, each camera 100, 105 controlled by the smart device110 includes a camera identifier, for example, a unique identificationnumber (e.g. a MAC address and the like). In this embodiment, the smartdevice 110 may receive and store the camera identifier when connectingto each camera. The smart device 110 may be configured to connect to andcontrol only certain cameras. For example, the smart device 110 mayinclude a pre-determined list of cameras with which it is compatible(e.g, cameras made by the same manufacturer as the smart device 110,cameras compatible with an application running on the smart device 110,etc.). In this example, if the smart device 110 connects to a camerawith which it is not compatible, the smart device 110 may display anincompatibility warning to a user of the smart device 110, and the smartdevice 110 may not be able to control the camera.

Prior to being controlled by the smart device 110, each camera connectedto the smart device 110 via the access point 120 may have an initialconfiguration, camera mode, and settings (referred to herein as an“initial mode”). For instance, each camera may an initial modereflecting the previous use of the camera, whether in conjunction withthe smart device 110 or use independent of the smart device 110. In oneembodiment, each camera has an independent initial mode. The smartdevice 110 may be configured to determine the initial mode of eachcamera and store the set of initial modes. In one embodiment, eachcamera automatically provides the camera's initial mode to the smartdevice 110 when connecting to the smart device 110. Alternatively, thesmart device 110 may query each camera for the camera's initial mode, ormay detect each camera's initial mode based on communications betweenthe smart device 110 and each camera.

After the smart device 110 connects to one or more cameras and storesthe initial modes of each camera, the smart device 110 may (as describedabove) change the camera mode of one or more of the connected camerasone or more times. After the smart device 110 (or the user of the smartdevice 110) is done controlling the one or more cameras, the smartdevice may retrieve the stored initial modes for the cameras, and maychange the configuration and camera mode of the one or more cameras tothe stored initial mode. This results in the cameras being configured tooperate with the same configuration and camera mode after beingcontrolled by the smart device 110 as before being controlled by thesmart device 110.

Alternatively, after the smart device 110 is done controlling the one ormore cameras, the smart device 110 may retrieve and transmit the storedinitial mode for each of the cameras to the cameras, and each camera maybe configured to configure itself to operate in the initial modereceived from the smart device 110 associated with the camera. Insteadof storing the initial mode of each camera at the smart device 110, eachcamera may store its initial mode prior to connecting to the smartdevice 110 at the camera, and may be configured to configure itself tooperate in the stored initial mode upon disconnecting from the smartdevice 110.

As discussed above, the smart device 110 may be configured to provide aninterface for controlling the one or more cameras to which the smartdevice 110 is connected. In the embodiment of FIG. 3, the interface isprovided via application 300. The application 300 may be a softwareapplication configured to run on a smart device 110. For example, thesmart device 110 may be a mobile phone, a laptop, a tablet computer, andthe like. Accordingly, the application 300 may be a software applicationconfigured to run on such a platform. Although in other embodiments, thesmart device 110 may provide other types of interfaces, the descriptionherein will be limited to the context of an application for the purposesof simplicity. This principles described herein apply equally to alltypes of interfaces.

The application 300 includes a user input module 305, a camera modemodule 310, a camera ID storage module 315, and an initial mode storagemodule 320. The user input module 305 is configured to provide any of avariety of user input mechanisms to allow the user of the smart device110 to interact with and/or control one or more cameras connected to thesmart device 110. For example, the user input module 305 may includebuttons (e.g., hardware or software buttons), and/or a touch-sensitivedisplay, allowing a user to identify one or more cameras and perform oneor more operations or interactions with the identified cameras. Varioususer input module 305 embodiments will be discussed below in greaterdetail.

The camera mode module 310 allows a user of the smart device 110 toadjust, change, or alter the camera mode of one or more camerasconnected to the smart device 110. For example, a user may instruct aset of cameras to begin recording video of a first object, may instructa second set of cameras to focus on a set object with varying zoomlevels and take pictures of the second object, may instruct all camerasto transmit live captured video and images to the smart device 110, andmay instruct all cameras to enter standby mode when finished. A user,via the camera mode module 310 of the application 300, may configure thecameras to change to any camera mode, setting, or configurationdescribed herein. In one embodiment, the camera mode module 310 storesthe initial mode of each camera to which the smart device 110 isconnected in the initial mode storage module 320. In this embodiment,the camera mode module 310 may change the camera mode of each camera towhich the smart device 110 is connected to the initial mode of thecamera (as discussed above) stored in the initial mode storage module320.

The camera data module 315 allows data to be streamed between the smartdevice 110 and the cameras connected to the smart device 110. In oneembodiment, a user may request, via the camera data module 315, to viewimages and video stored on a camera (e.g., the camera 100) connected tothe smart device 110. In this embodiment, the camera data module 315 mayrequest image and/or video data stored on the camera 100, and inresponse, the camera 100 provides the image and/or video data to thesmart device 110 via the access point 120. The camera data module 315may then display the retrieved images and/or video on the smart device110 to the user, for instance in a image/video user interface. Anymethod of displaying or navigating images and videos on a smart device110 may be used (e.g., tiled content thumbnails, full-screen display,etc.), and thus the display of images and videos on the smart device 110will not be discussed further for the purposes of brevity.

In addition to stored images and video, the camera data module 315 maybe configured to allow a user the ability to stream live video and toview images as they are taken. For example, a user may request, via thecamera data module 315, to stream video being taken by 6 differentcameras on the smart device 110 (e.g., as part of a home securitysystem). In this example, each camera sends a live video stream to thesmart device 110 via the access point 120, and the camera data module315 displays the 6 video streams on the smart device 110.

The camera data module 315 may be configured to transfer data to thecameras to which the smart device 110 is connected. In one embodiment,the camera data module 315 is configured to transmit software, firmware,or hardware updates to cameras connected to the smart device 110.Likewise, the camera data module 315 may provide an interface for a userof the smart device 110 to manually manage the credentials stored by theone or more cameras (e.g., cameras 100, 105). In addition, the cameradata module 315 may be configured to transmit any additional data,either related to or unrelated to the operation of the cameras, to thecameras.

The camera data module 315 may allow a user to use the smart device 110as an electronic viewfinder for one or more cameras (e.g., cameras 100,105). The camera data module 315 may request from one or more camerasthe current “view” of the camera, representing the light entering eachof the one or more camera's lenses, and in response, each of the one ormore cameras transmit the current view of the camera to the smart device110. The views are then displayed by the camera data module 315 on thesmart device 110. In this embodiment, a user may then use the cameramode module 310 to adjust the current view of the camera, to adjust thecamera mode or settings to alter the current view of the camera (e.g.,by zooming in/out or moving the camera to point in a differentdirection), or to capture the current view as an image or video.Further, in this embodiment, each of the one or more cameras maycontinually transmit a current view of the camera such that the cameradata module 315 may display a real-time view for the camera.

The camera data module 315 may provide a user with an interface forediting images and/or video received from one or more cameras (e.g.,cameras 100, 105) on the smart device 110. For instance, a user may usethe user input 305 of the smart device 110 to re-size images and videos,to crop images and videos, to adjust start and stop times of video, toadjust the size or resolution of images and videos, to re-encode imagesand videos, and the like. The camera data module 315 may store any datareceived from any camera to which the smart device 110 is connected inthe camera data storage module 325. For instance, images and video(either live or previously captured) sent from a camera to the smartdevice 110 may be stored in the camera data storage module 325.Likewise, video or images from a camera connect to the smart device 110but edited at the smart device 110 may be stored at the camera datastorage module 325.

In one embodiment, the application 300 stores information identifyingone or more cameras (e.g., cameras 100, 105) in the camera ID storagemodule 330. For example, if each camera connected to the smart device110 via the access point 120 includes an identification number that mustbe provided to the camera prior to interacting with the camera, theapplication 300 may receive the identification number from the camerawhen connecting to the camera and may store the camera identificationnumber in the camera ID storage module 330. In this example, when a userof the application 300 wants to interact with a particular camera, theapplication 300 may retrieve the identification number for theparticular camera from the camera ID storage module 330, and may providethe identification number to the particular camera prior to interactingwith the camera. Any type of information identifying a camera may bestored in the camera ID storage module 330, such as an identificationnumber, an IP or MAC address, a camera password, camera credentials, andthe like. The identifying information stored in the camera ID storagemodule 330 may be used to communicate with a camera, to identify acamera to which the smart device 110 has previously connect, toauthenticate the smart device 110 or a user of the smart device 110 to acamera, and so forth.

It should be noted that any of the functionality described above withregards to the application 300 may be performed by the smart device 110without the use of an application. Likewise, it should be noted that anyof the functionality performed by the smart device 110 may be performedby a remote control 340. In one embodiment, the smart device 110 is aremote control 340. Alternatively, the embodiment of FIG. 3 may beimplemented via a smart device 110 and a remote control 340, which mayboth be coupled to one or more cameras, either directly or via theaccess point 120. For example, the smart device 110 may receivestreaming video from one or more cameras, and the remote control 340 maybe used to start and stop the streaming video. Further, the remotecontrol 340 may receive credentials for the one or more cameras or theaccess point 120 via the smart device 110, the smart device 110 mayreceive credentials for the one or more cameras via the remote control340, and the cameras may receive credentials for the access point 120 orthe smart device 110 from the remote control 340. In one embodiment, theremote control 340 is able to operate in access point mode, and is ableto connect to multiple cameras. In this embodiment, unlike the smartdevice 110, the remote control 340 may provide the credentials of theaccess point 120 to multiple cameras simultaneously.

Theinternal storage modules 422 and 428 are, in one embodiment, integratedhard disk drives or solid state memory devices, though in otherembodiments may be removable memory devices, such as writeable compactdiscs or DVDs, removable hard disk drives, or removable solid statememory devices. The memories 414 and/or the internal storage modules 422and 428 are configured to store instructions and data that can beexecuted by the processors 412 to perform the functions related to theprocesses described herein. The memories 414 and the internal storagemodules 422 and 428 may be configured to store image or video datacaptured by the camera 100. It should be noted that in one embodiment,the internal storage modules 422 and 428 are implemented in the samemodule within the camera 100 as the memories 414 a and 414 b,respectively.

The network adapters 416 a, 416 b, 416 c, and 416 d (hereinafter“network adapters 416”) communicatively couple the components of theembodiment of FIG. 4 via the connecting network 400. Each networkadapter 416 may include a network card, a modem, or any deviceconfigured to allow the camera 100, the smart device 110, the accesspoint 120, and the remote control 340 to inter-communicate via theconnecting network 400 and vice versa.

The image sensor chip 408 converts light into an electronic signal. Forexample, to take an image of the scene in front of the camera 100, theimage sensor chip 408 of the camera 100 captures the light reflected offobjects in the scene, and converts the photons of the captured lightinto an electronic signal, such as voltages. The image sensor chip 408may include any of a variety of image sensors for use in a camera, suchas a charge-coupled device image sensor (“CCD”), or a complementarymetal-oxide-semiconductor image sensor (“CMOS”). The image sensor chip408 may convert light into pixel color information using, for example, abayer sensor or the like.

The DSP chip 410 may convert the captured image information into any ofa variety of image formats, such as the JPEG, BMP, GIF, or PNG formats,or any other suitable image format. Likewise, the DSP chip 410 mayconvert the captured image information into any of a variety of videoformats, such as the MOV, AVI, WMV, or MKV formats, or any othersuitable image format. The DSP chip 410 may apply any of a variety ofencoding techniques, either lossless or lossy, such as the MPEG-2,MPEG-4, h.264, or VC-2 formats. The DSP chip 410 may perform any of avariety of filtering functions, in both the time/space domain andfrequency domain. The DSP chip 410 may also perform any of a variety offormatting functions, such a cropping, up- or down-conversion ofresolution, color/contrast/brightness adjustment, compression, or anyother suitable image or video processing function.

The user input 418 may include one or more buttons on the exterior ofthe camera 100, and allows a user of the camera 100 to interact with thecamera 100. Alternatively, the user input 418 may include a touch-screencomponent of the local display 420, an external input device, such as akeyboard, mouse or other controller configured to communicate with thecamera 100 via an input port or the network adapter 416 a, or any othermeans of interacting with the camera 100. A user may use the user input418 to perform functions of the camera 100, such as navigating throughpreviously captured images or video, editing or deleting previouslycaptured images or video, altering the camera's settings (such as theresolution or frame rate of future captured images or video, adjusting apower-save mode, or adjusting other camera parameters or settings, suchas a night/day mode, a self-timer, an exposure length, and the like),altering the communication mode of the camera (such as switching betweenaccess point, ad hoc, and station mode, or cycling through allcommunication modes), detecting and connecting to other wireless devicesvia the network adapter 416 a, obtaining the wireless credentials ofanother device, turning the camera 100 on and off, communicating withexternal modules via the network adapter 416 a, and so forth. The userinput 418 may include a very limited number of buttons or otherinterface mechanisms, for instance as few as one or two.

The local display 420 may be implemented with an integrated LCD screenor other similar screen, such as a monochromatic display or otherdisplay. Alternatively, the local display 420 may be implemented with aremovable display module, such as a LCD pack configured to couple to thecamera 100 and communicate with the components of the camera 100 throughan internal bus.

The local display 420 may be configured to operate as a user interfacefor a user of the camera 100. In one embodiment, the local display 420displays menus, HUDs, UIs, and the like to allow a user to utilize thefunctionalities of the camera 100 or to inform the user of informationrelated to the camera 100, such as the amount of available storageremaining, the amount of power remaining, the current resolution and/orframe rate of the camera 100, the communication mode of the camera, andany other settings or information related to the camera 100. In oneembodiment, the camera 100 is configured to perform the functions of anelectronic view finder, allowing a user of the camera 100 to view theimages and/or video that the camera 100 will capture, is capturing, orhas previously captured.

The local display 420 may be configured to display information relatedto other devices. For example, the local display 420 may display otherwireless devices capable of communicating with or connecting to thecamera 100 via the connecting network 400. In addition, the localdisplay 420 may display the identity of one or more devices to which thecamera 100 is connected. The local display 420 may also displaycredential information related to the camera 100. For example, if thelocal display 420 is displaying a list of devices that the camera 100has detected, the local display 420 may also display an indication ofthe devices for which the camera 100 possesses the credentials. A usermay utilize the local display 420 in conjunction with the user input 418to select an communication mode for the camera 100, to select one ormore devices to connect to, to select one or more devices to obtaincredentials for, to select one or more devices to transmit credentialsto, and the like.

The user input 424 of the smart device 110 is configured to allow a userof the smart device 110 to interact with the smart device 110. The userinput 424 may be implemented with any of a variety of smart device 110user input interfaces, such as a keyboard, a keypad, a mouse, atouch-screen interface, a voice-controlled interface, and the like. Ingeneral, the user input 424 of the smart device 110 allows for greateruser-interface capability than the user input 418 of the camera 100,though this is not necessarily the case. Likewise, the user input 430 ofthe remote control 340 may contain a similar interface as the user input418 of the camera 100 (for instance by having the same number ofbuttons), or may contain a different interface of lesser or greatercomplexity and flexibility. It should be noted that in instances whenthe smart device 110 is coupled to the camera 100, the user input 424may allow a user of the smart device 110 to control and interact withthe camera 100 via the smart device 110. Likewise, when the remotecontrol 340 is coupled to the camera 100, the user input 430 may allow auser of the smart device 100 to control and interface with the camera100 via the remote control 340.

The connecting network 400 enables communications among the entities towhich the connecting network 400 is coupled. In one embodiment, theconnecting network 400 is the internet and uses standard communicationstechnologies and/or protocols. Thus, the connecting network 400 caninclude links using technologies such as Ethernet, 802.11, Wifi,worldwide interoperability for microwave access (WiMAX), long termevolution (LTE), GSM, CDMA, EDGE, 3G, and any other wired or wirelesscommunicative protocol and standard. Similarly, the networking protocolsused on the connecting network 400 can include multiprotocol labelswitching (MPLS), the transmission control protocol/Internet protocol(TCP/IP), the User Datagram Protocol (UDP), the hypertext transportprotocol (HTTP), the simple mail transfer protocol (SMTP), the filetransfer protocol (FTP), and the like. The data exchanged over theconnecting network 400 can be represented using technologies and/orformats including the hypertext markup language (HTML), the extensiblemarkup language (XML), and the like. At least a portion of theconnecting network 400 can comprise a mobile (e.g., cellular orwireless) data network such as those provided by wireless carriers. Insome embodiments, the connecting network 400 comprises a combination ofcommunication technologies.

Operational Configurations

FIG. 5 illustrates an embodiment of a process for detecting devices in acamera system. The camera is configured 500 to operate as an accesspoint. The camera may initially be configured to operate in stationmode, in a standby mode, or in a startup mode, or the camera mayinitially be powered off. Configuring the camera to operate as an accesspoint may include configuring the camera to cycle from station modethrough various modes including access point mode. Likewise, configuringthe camera to operate as an access point may includes configuring thecamera to switch from standby mode, startup mode, or from being poweredoff into access point mode. Note that in one embodiment, configuring thecamera to operate as an access point may include configuring the camerato operate in ad hoc mode.

The availability of one or more client wireless devices configured tooperate as wireless stations is determined 510. In one embodimentdetecting client wireless devices configured to operate as wirelessstations involves using the association mode of a wireless protocol,such as Wifi. In an alternative embodiment, detecting client wirelessdevices may include sending out query signals from the camera within acommunicative range of the camera to detect client wireless devicesoperating as wireless stations or in station mode able to communicatewith the camera and within the communicative range of the camera. Thequery signals may be configured to cause any devices operating aswireless stations or in station mode to transmit an identifying signalfrom the wireless device to the camera, the identifying signal includinginformation identifying the wireless device to the camera. Any suitablemethod of detecting client wireless devices operating in as wirelessstations may be used, including those utilized by the wireless standardsdiscussed herein, or any proprietary method. It should be noted that theclient wireless devices configured to operate as wireless stations maybe devices incapable of operating as wireless access points, and thusare only detectable when the camera is configured to operate as awireless access point.

Responsive to detecting 520 an available client wireless deviceconfigured to operate as a wireless station, the camera connects 530 tothe client wireless device. Connecting to a client wireless device mayinvolve the passing of wireless credentials between the camera and theclient wireless device. In the event that the camera does not possessthe required credentials for the client wireless device, the attempt bythe camera to connect to the client wireless device may be rejected bythe client wireless device. In such a circumstance, the camera mayobtain the credentials from an alternative source and may re-attempt toconnect to the wireless device. In one embodiment, the camera may not berequired to possess the wireless credentials for the client wirelessdevice; in such an embodiment, the camera may immediately connect to theclient wireless device.

Responsive to failing to detect 520 an available client wireless deviceconfigured to operate as a wireless station, the camera is configured540 to operate as a wireless station. In one embodiment, an availableclient wireless device configured to operate as a wireless station is aclient wireless device to which the camera has not previously connected.In this embodiment, if the camera previously connects to the clientwireless device and subsequently disconnects from the client wirelessdevice, the client wireless device is no longer “available” from theperspective of the camera in detecting client wireless devicesconfigured to operate as a wireless station with which to connect.

The availability of one or more client wireless devices configured tooperate as a wireless access point is determined 550. Similarly todetermining the availability of one or more client wireless devicesconfigured to operate as a wireless station, determining theavailability of one or more client wireless devices configured tooperate as wireless access points may involve using the association modeof a wireless protocol, using device-identifying ping signals configuredto cause client wireless devices operating as wireless access points toidentify themselves with response signals, or any other suitable methodof detecting client wireless devices operating as wireless accesspoints.

Responsive to detecting 560 an available client wireless deviceconfigured to operate as a wireless access point, the camera connects570 to the client wireless device. As discussed above, connecting to theclient wireless device configured to operate as a wireless access pointmay require the camera to possess the wireless credentials of the clientwireless device and may require the camera to obtain the wirelesscredentials of the client wireless device if the camera does not possessthe wireless credentials. Responsive to failing to detect 560 anavailable client wireless device configured to operate as a wirelessaccess point, the camera enters 580 standby mode. In one embodiment,entering standby mode includes configuring the camera to continue tooperate as a wireless station. Alternatively, entering standby mode mayinclude configured the camera to operate in a power-saving mode, acommunication-free mode, a communication-slowdown mode, or may cause thecamera to power off.

The process of the embodiment of FIG. 5 may be repeated any number oftimes as needed, causing the camera to cycle between operating as awireless access point and a wireless station, detecting various clientwireless devices configured to operate both as wireless stations oraccess points. In various embodiments, the process of FIG. 5 may beaugmented to allow a user of a camera to select one or more of manyclient wireless devices with which to connect, and may include variousmeans for obtaining the wireless credentials of one or more clientwireless devices, for instance as discussed in the embodiments of FIGS.6-8.

FIG. 6 illustrates an embodiment of a process for transferringcredentials in a camera system. FIG. 7 is a timing diagram illustratingthe operation of an embodiment of a process for transferring credentialsin a camera system, and will be discussed in the context of FIG. 6.FIGS. 6 and 7 are described herein in the context of the camera systemof FIGS. 1-4. In the embodiments of FIGS. 6 and 7, the camera 100initially does not possess the wireless credentials required to connectto a communication device configured to operate as an access point, andthe smart device 110 initially may possess the wireless credentialsrequired to connect to the communication device configured to operate asan access point. The remainder of the description herein will refer tothe communication device configured to operate as an access point as theaccess point 120, though in other embodiments, the communication devicemay be any device configured to operate as a wireless access point andto connect to devices that possess the communication device's wirelesscredentials.

Although not illustrated in the embodiment of FIGS. 6 and 7, the camera100 may initially be configured to operate in station mode, and maydetect and attempt to connect to the access point 120. In response tothe attempt to connect, the access point 120 may query the camera 100for the wireless credentials required to access the access point 120. Inresponse to such a query, the camera 100 indicates to the access point120 a lack of the required credentials, and the access point 120 deniesthe connection attempt.

The camera 100 is configured 600 to operate in access point mode. Thisis illustrated in FIG. 7 as access point mode 700. In one embodiment,the camera 100 is configured to operate in access point mode responsiveto a denied connection attempt by the access point 120. In response tothe denied connection attempt, the camera 100 may detect the smartdevice 110 as an available wireless device possessing the wirelesscredentials required to connect to the access point 120. The camera 100is then configured to connect 610 to the smart device 110. Asillustrated in FIG. 7, the camera 100 connects 706 to the smart device110.

Wireless credentials are received 620 from the smart device 110 for theaccess point 120. In the embodiment of FIG. 7, receiving wirelesscredentials from the smart device 110 for the access point 120 involvesthe camera 100 sending 708 a request to the smart device 110 for thewireless credentials of the access point 120. In one embodiment, thesmart device 110 already possesses the wireless credentials for theaccess point 120, and sends 712 the wireless credentials to the camera100. Alternatively, the smart device 110 may retrieve the wirelesscredentials from the access point 120 by requesting 708 the wirelesscredentials from the access point 120. Such a request may require thesmart device 110 to identify itself to the access point 120, to identifythe camera 100 to the access point 120, or to provide additionalinformation involving the camera 100, the user of the camera 100, thesmart device 110, the user of the smart device 110, or any otherinformation related to the operation of the camera 100 or the smartdevice 110. Responsive to receiving the request for wireless credentialsfrom the smart device 110, the access point 120 may approve the requestand may send 710 the wireless credentials for the access point 120 tothe smart device 110, for subsequent sending 712 to the camera 100.

In response to receiving the wireless credentials for the access point120 from the smart device 110, the camera 100 is configured 630 tooperate as a wireless station. In one embodiment, by switching fromoperating as a wireless access point to operating as a wireless station,the camera 100 may disconnect from the smart device 110, particularly ifthe smart device 110 is incapable of operation as an access point,thereby requiring another device to operate as an access point in orderto connect to the other device. In other embodiments, the camera 100 isnot configured to operate as a wireless station, and instead continuesoperation as a wireless access point. It is noted that configuring thecamera 100 to operate as a wireless station may improve the powerefficiency and performance of the camera 100. Configuring the camera 100to operate as a wireless station is represented as station mode 714 inFIG. 7.

The camera 100 connects 640 to the access point 120 using the wirelesscredentials received for the access point 120 from the communicationdevice. As illustrated in FIG. 7, the camera 100 connects 716 to theaccess point 120 directly, bypassing the smart device 110, using thewireless credentials for the access point 120. Once the camera 100 isconnected to the access point 120, the smart device 110 may also connectto the access point 120. The smart device 110 may then logically connectto the camera 100 via the access point 120, without directly connectingto the camera 100. Thus, communications may be sent from the smartdevice 110 to the access point 120, which are then forwarded to thecamera 100. Likewise, communications may be sent from the camera 100 tothe access point 120, which are then forward to the smart device 110. Insuch a way, the smart device 110 may control and interact with thecamera 100 via the access point 120 without a direct connection to thecamera 100, and may receive video and images from the camera 100 via theaccess point 120.

FIG. 8 illustrates an embodiment of a process for transferringcredentials within a camera system. Wireless credentials are received800 at a first camera for a communication device. The wirelesscredentials may be received wirelessly from a smart device, which mayobtain the wireless credentials in advance or which may retrieve thewireless credentials from the communication device or elsewhereresponsive to a request from the first camera. Alternatively, thewireless credentials may be received via a wired connection with a smartdevice, for example via a USB port or an audio port configured toreceive the wireless credentials encoded into audio signals. In oneembodiment, the wireless credentials may be encoded into an image anddisplayed to the first camera, and the first camera may be configured tocapture the displayed image and decode the captured image to retrievethe wireless credentials. Any suitable means of receiving the wirelesscredentials at the first camera may be used. The communication devicemay be configured to operate as a wireless access point, and thewireless credentials may be configured to allow a wireless devicepossessing the wireless credentials to connect to and communicate withthe communication device.

The first camera is then configured 810 to operate as an access point.In one embodiment, this involves configuring the first camera to operatein access point mode. A second camera configured to operate as awireless station is detected, and the first camera is configured toconnect 820 to the second camera. In an alternative embodiment, insteadof configuring the first camera to operate as an access point andconfiguring the second camera to operate as a wireless station, thefirst camera and the second camera may instead be configured merely todetect each other, connect to each other, and for the first camera totransmit wireless credentials to the second camera.

The wireless credentials received by the first camera are sent 830 tothe second camera. The second camera 840 then connects 840 to thecommunication device using the received wireless credentials. In oneembodiment, the first camera subsequently is configured to operate as awireless station and is configured to connect to the communicationdevice using the received wireless credentials. This process may berepeated for any number of additional cameras, wherein the first camerasends the wireless credentials for the communication device toadditional cameras, and wherein the additional cameras each connect tothe communication device using the wireless credentials.

In one embodiment, the first camera is configured to send the wirelesscredentials for the communication device to multiple additional camerassimultaneously. Such an embodiment is possible if the first camera isconfigured to operate as a wireless access point, and each of theadditional cameras is configured to operate as a wireless station, sinceone wireless access point is able to connect to multiple wirelessstations simultaneously. By simultaneously transmitting credentials tomultiple addition cameras, the amounts of time required to transmit thecredentials from the first camera to the additional cameras and for theadditional cameras to connect to the communication device are minimized,resulting in an increase in performance efficiency. Further, such aprocess prevents a user from having to individually transfer thecredentials to each camera; for embodiments with tens or hundreds ofcameras, the amount of effort saved in transferring the wirelesscredentials to each camera may be significant.

FIG. 9 illustrates an embodiment of a process for managing cameraoperation modes in a camera system. A connection is established 900between a smart device and one or more cameras. At the time ofconnection, each of the one or more cameras may be configured to operatein a particular operation mode (referred to herein as the “initial” modeof each camera). The smart device may be a mobile phone, a tabletcomputer, a remote control, or any device capable of connecting andinterfacing with one or more cameras. In one embodiment, the connectionis established between the smart device and the one or more camerasthrough a communication device configured to operate as an access point,such as a Wifi access point, a mobile phone communication tower, or anyother communication device configured to allow the smart device tologically connect to the one or more cameras via the communicationdevice.

The initial mode of each of the one or more cameras is identified 910.In one embodiment, each camera identifies its initial mode to the smartdevice after connecting to the smart device. Alternatively, the smartdevice may query each camera to determine the initial mode of eachcamera. The initial modes are all then stored 920 for subsequentretrieval. As referred to herein, storing the initial modes of eachcamera may comprise merely storing an initial mode identifier, orstoring configuration information describing the initial mode. Theinitial mode of each camera may be stored at the smart device, may bestored at each camera, or may be stored elsewhere by the smart device.

During the course of operation and interaction between the smart deviceand the one or more connected cameras, the modes of the one or morecameras are changed 930 from the initial mode of each camera to a secondmode. In one embodiment, the smart device changes the mode of each ofthe cameras. For instance, the smart device may present an interface toa user of the smart device allowing the user to change the mode of thecameras. As discussed above, changing the mode of the camera may includechange the camera mode of the camera (for example, between image mode,burst image mode, video mode, high-speed video mode, and the like), thepositioning and orientation of the camera, the zoom of the camera, thecapturing of images and videos, and the like. The mode of each cameramay be changed any number of times, though reference will only be madeherein to the initial mode and the second mode for the purposes ofsimplicity.

A determination is made 940 to revert each of the one or more cameras tothe initial mode of each camera. In one embodiment, making such adetermination includes determining to disconnect the one or more camerasfrom the smart device. Alternatively, making such a determination mayinclude providing an interface on the smart device for a user tomanually revert the modes of each of the one or more cameras to theinitial mode of each camera. For example, the smart device may beconfigured to operate a program which provides a button that, whenselected by a user of the smart device, reverts the mode of each camerato the initial mode of each camera.

Responsive to determining to revert each of the one or more cameras tothe initial mode of each camera, the stored initial mode for each camerais retrieved 950. In one embodiment, the smart device retrieves thestored initial mode for each camera. Alternatively, each camera mayretrieve the initial mode for itself, for example in the embodimentwhere the initial mode of each camera is stored at each camera. The modeof each of the one or more cameras is changed 960 to the retrievedinitial mode of each camera. In one embodiment, changing the mode of acamera to the initial mode of the camera includes the smart devicetransmitting the initial mode (or an identifier of the initial mode orconfiguration information describing the initial mode) to the camera,and the camera switching itself to the received initial mode. In theembodiment where a camera stores the initial mode of itself at thecamera, the smart device may merely instruct the camera to change to thestored initial mode and the camera, responsive to receiving such aninstruction, converts itself to the initial mode it is storing.

It should be noted that in one example embodiment, the mode of only aportion of the one or more cameras is changed from an initial mode to asecond mode; in such an embodiment, the mode of only the portion of theone or more cameras is reverted to the initial mode of each camera inthe portion of the one or more cameras. Similarly, in one embodiment, adetermination is made to revert only a portion of the one or morecameras to the initial mode of each camera, for instance by determiningto disconnect only the portion of cameras from the smart device. In suchan embodiment, the mode of only the portion of the one or more camerasis reverted to the initial mode of each camera in the portion of the oneor more cameras.

The process of FIG. 9 allows a user of the one or more cameras to setthe one or more cameras up in a particular configuration, to connect asmart device to the one or more cameras, to control/interact/change themode of the one or more cameras with the smart device, and then torevert the one or more cameras to the original configuration. Such aprocess beneficially allows the user to quickly adapt and modify themodes of the one or more cameras temporarily, without a loss of the timeand effort put into establishing the original configuration of the oneor more cameras. Thus, a user may precisely configure the cameras forlong-term operation, may quickly re-configure the cameras for short-termoperation, and then may revert the cameras to the original configurationwith very little additional effort on the part of the user.

The camera system described herein beneficially allows for thetransferring of wireless credentials between a camera and anotherdevice, preventing the need to manually enter the wireless credentialsdirectly into the camera via a camera's limited input means andmechanisms. The camera described herein can detect another device byswitching between operation as a wireless station and as a wirelessaccess point. Such a configuration beneficially allows the camera todetect devices configured to operate only as wireless stations whilesimultaneously optimizing the amount of time the camera itself isconfigured to operate as a power-efficient wireless station. Usingsimilar means and mechanisms, the camera can then wirelessly transmitthe received credentials to other cameras simultaneously, increasing theefficiency of the system. Finally, by preserving the initial mode ofeach of one or more cameras wirelessly coupled to a smart device, thecamera system can efficiently revert each camera to the operating modeof the camera prior to coupling to the smart device, saving the user ofsuch cameras from having to manually revert each camera mode.
